FAQs
What is a Letter of Medical Necessity?
A Letter of Medical Necessity (LMN) is a physician-signed statement confirming that a specific product, service, or program is medically necessary for your care. It's the documentation HSA, FSA, and HRA plans, insurers, employers, and schools often require before approving or reimbursing an expense.
What can a Letter of Medical Necessity be used for?
An LMN is most commonly used to unlock pre-tax reimbursement through an HSA, FSA, or HRA for dual-purpose items like gym memberships, wearables, or massage therapy. It also supports insurance appeals and prior authorizations, workplace accommodations under the ADA, school accommodations under Section 504 or an IEP, and medical-hardship contract cancellations.
Do I qualify for a Letter of Medical Necessity?
Most people with an ongoing health condition may qualify. The intake form asks about your health background and the specific expense or approval you're seeking. A licensed physician reviews the case and, when clinically appropriate, issues the letter.
Who signs the letter?
A board-certified physician licensed in your state reviews your case and signs the letter under their own name, medical license, and NPI. That physician's identification is printed on the letter, which is what any reviewer uses to verify it.
Can I use my HSA or FSA for a gym membership or wearable?
In many cases, yes. Expenses like gym memberships, personal training, wearables, and ergonomic equipment may qualify for reimbursement when a physician determines they are medically appropriate and issues a Letter of Medical Necessity. Final decisions are made by your plan administrator.
Can I use my letter for workplace or school accommodations?
Yes. A signed letter is commonly used to support requests for reasonable workplace accommodations under the ADA (such as standing desks, ergonomic seating, or schedule adjustments) and school accommodations under Section 504 or an IEP. Individual employer and school policies still apply.
How fast will I receive my letter?
Most letters are reviewed and delivered within 24-48 hours of submission. More complex cases may take up to a few days. Requests can be made at any time, with availability 24/7 including evenings, weekends, and holidays.
What happens if my request is not approved?
A licensed physician issues a letter only when it is medically appropriate based on your responses. If your request is not approved, you're covered by our money-back guarantee. See our Payment and Refund Policy for full details.
How long is my letter valid?
Most letters are valid for the current plan year. If your condition and treatment plan continue into the following year, you can request a renewal.
Is my information kept private?
Yes. We're fully HIPAA compliant. Any verification with a third party confirms only that your letter is valid, never your diagnosis or health details. See our HIPAA Compliance policy for full details on how we protect your information.
